My SR2 has an SPDIF header, alongside the normal audio header. But the mobo did not come with an adapter, and I have hunted high and low, not hits so far. Do you know of any?
What I want is just a bracket that I can put in one of the slots, with an RCA connector. No optical connector, no coax, just an RCA. The header on the MOBO has two (correct me if I am wrong) connectors. I could make my own, but better just buy one.
Do you happen to know what brand is making things like this? And while I am at it, it is a pity EVGA did not supply it with the mobo..

What moose said is correct.  The SPDIF header was intended for use with graphics cards.  Cards prior to the 400 series needed this cable attached for HDMI sound.  If you really want to use another connector besides the 3.5mm, you will have to consider buying a sound card.

Funny thing is.. I been dealing with the same issue and your post got me to goole a little and found a few.. then I realized Ive got a few out in my old parts box so im going to try and hook em up.. Ive listening to my processors.. mouse laser and a bevy of other sounds because I hacked together an unshielded analog audio cable to get quick sound.
 
 

Sweet!! thanks for getting my ass in gear.. it works! 
  
careful not to use the 5v.. the first pin on the left
 

 

 
Its "other models" .. pin 1 is 4.899 som odd volts

Im just stoked the OP's P got me to look closer and now I dont need to go buy an X-Fi just to get a single digital out for audio..
It sounds great.. it spits out a 24bit 192000hz studio quality signal and passes dolby prologic through to my surround reciever

Thanks a lot!
I just ordered this:

It will take some time before it arrives, but I can use my time better than making such a device myself.  And with a total cost of $13 including shipment, it is not a big risk Besides of this, maybe I also want to use the optical connections, my Motu has two optical channels inputs, and only one rca.
As I said, I will post a follow-up.

the optical is what dosent work and probably the reason evga didnt give us the out bracket

So optical doesn't work?

..  and now obviously it works. Maybe somthing changed in the newer bios.

I don't think it is like this, but I am not sure. But this is how I assume it works:
The SPDIF output is digital TTL technology. That means, plus 5 Volt for digital 1, and 0 Volt for digital 0. This way, a chain of 1s and 0s come from the pin on the SPDIF header on the SR2 PCB, and you can then connect a cable to any device that accepts SPDIF input, i.e. accepts a chain of 1s and 0s which is 5 Volt and 0 Volt respectively.
When it comes to the optical connection, I think it is very simple. As LED is turned on and off, corresponding to 1s and 0s in the digital chain. You just have to supply the LED with power, and a simple digital switch, which is governed by the SPDIF digital. The power needed for the LED is taken from the third pin on the SR2 PCB, which  is 5V. But it could as well have been taken from a battery or any external power source. My point here, to sum it up, is that there is no advanced logic behind this at all. And the BIOS is definitely not involved.
I only assume, but I think it has to be like this. If this is correct, it just has to work, as simple as that.

Hi everybody! here is an update.
I ordered this:

For $9 I have a completely new world for my multi media PC. It worked immediately, just plugged it in, and connected it to my MOTU breakout box. It worked as expected!!!
Having struggled almost one day with bit rates and settings, I finally had everything working fine. For some reason, my system, the MOTU, has problems with 96 kHz 24 bit, but 88.2 kHz 24 bit works just great.
Hooray! :)

What model MOTU interface are you using?

I have this: http://www.motu.com/products/motuaudio/828mk3

I will try to explain again why this is so fantastic.
If you work with multimedia, and especially sound, the application in question will command the MOTU (or any other box) to use certain sample rates and bit rates. The standard 44.1 kHz 16 bit is fine for final results, but if you have stuff you want to process using effects, you most likely want a higher resolution. When working with the DAW Cakewalk Sonar, I use 88.2 kHz 24 bit. This is fine as long as only Sonar is on. But what if I want to add a sound to the mix, that I find on the Internet? Windows works with 44.1 and a conflict occurs. Either Internet is silent, or Sonar is silent, and you get a lot of nasty error messages and sometimes I even had to reboot my computer.
Using the S/PDIF, I can have Windows use the onboard Realtek audio device. And then send this sound out in a digital format to the MOTU box, and use the built in mixer in the MOTU to mix everything together.
So now I can work at high resoultion in Sonar, and at the same time listen to YouTube, download sound clips, mix and match, no problems anymore.
This little device I bought changed everything! Pity it did not come with the SR2 mobo, but maybe few will use it like this.
